...give you four numbers, 00, 01, 10 and 11, which are the binary-number equivalents of good old 0, 1, 2 and 3. Three ambiguities give eight numbers, and so on, until with 50 you have a million billion numbers represented simultaneously in the quantum computer. In theory the machine can compute with all of them at the same time. Such quantum spookiness spooks the spooks. The world's secret services are still engaged in the centuries-old contest between code-makers and code-breakers. There are new concepts called quantum one-time pads for a supposedly...

...cultural values and genital surgery are illuminated in the process of “assigning” sex. “Atypical” is often demarcated on the basis of size: an enlarged clitoris or a small penis. But why should a clitoris that is larger at birth than the typical range of 0.2 to 0.85 centimeters or a penis that is smaller than 2.5 to 4.5 centimeters be considered a reason to perform genital surgery? Here heterosexism interacts with the two-sex economy to lead to an expectation not only of two (and only two) differentiated genitals but also of genitals that can (only) accomplish...
